Initially, Mudkip was distrustful of strangers and was very protective of those it cared for. Once Brock gained its trust, Mudkip became an extremely loyal Pokémon and felt safer around strangers.
Mudkip was shown to be more of a sensible type and assisted Pikachu with breaking up and resolving arguments between the other Pokémon. It is also friendly with younger Pokémon.
When Mudkip evolved into Marshtomp, it developed a flirtatious side, like its Trainer, as seen when it fell madly in love with Mariah's Flaaffy.
